WebWe can therefore correctly infer that period 3 elements all have three electron shells. However, they have different numbers of electrons. An element's atomic number tells us … WebIn period 3, all of the elements have three electron shells. This also means that they have the same number of inner electron shells. The inner electron shells shield the outer electron shell from some of the charge of the nucleus. The attraction between the remaining charge of the nucleus and the outer electron shell determines atomic radius ...

8.3: Electron Configurations- How Electrons Occupy Orbitals

WebAnswer (1 of 2): As you know, oxygen electrons occupy only two shells: the first and second ones. The first shell contains the 1s subshell, capable of holding 2 electrons. The second shell contains the 2s and 2p subshells, capable of holding 2 + 6 = 8 electrons. In oxygen, the first shell is co... marcello d\u0027orta io speriamo che me la cavo

2.6: Arrangements of Electrons - Chemistry LibreTexts

WebMay 11, 2024 · Oxygen starts with six valance electrons and ends with six valance electrons but after bonding has parts of the densities of 8 electrons Explanation: Chemical bonding does not increase the valance electrons. Oxygen has 6 valence electrons. Bonding is sharing of valance electrons WebO + 2e – → O 2-. Here, the electron configuration of oxide ion (O 2-) is 1s 2 2s 2 2p 6. This electron configuration shows that oxide ion (O 2-) have two shells and the second shell has eight electrons and it acquired the electron configuration of neon. That is, in this case, the valence of oxygen ions is -2. WebAs you can see, oxygen has eight electrons. In fact, the oxygen atom has six valence and two core electrons. The number of valence and core electrons in an atom is equal to the … marcello fantoni for raymor
